Laplace transform of \(\cos \left( {{\rm{\omega t}}} \right){\rm{is}}\frac{{\rm{s}}}{{{{\rm{s}}^2} + {{\rm{\omega }}^2}}}\). The laplace transform of e-2t cos(4t) is

• A. \(\frac{{{\rm{s}} - 2}}{{{{\left( {{\rm{s}} - 2} \right)}^2} + 16}}\)
• B. \(\frac{{{\rm{s}} + 2}}{{{{\left( {{\rm{s}} - 2} \right)}^2} + 16}}\)
• C. \(\frac{{{\rm{s}} - 2}}{{{{\left( {{\rm{s}} + 2} \right)}^2} + 16}}\)
• D. \(\frac{{{\rm{s}} + 2}}{{{{\left( {{\rm{s}} + 2} \right)}^2} + 16}}\)
